The wikipedia article [1] is a decent introduction. Functional programming is loosely-defined as a style of programming that involves using some subset of:
* Higher-order functions
* Pure functions / referential transparency
* Immutability
* A powerful type system
* A declarative style (expression-based)
(Some of the above concepts are closely related, and some people may feel there are other important ones I left out)
A functional programming language is loosely-defined as a language which makes programming in the above style possible, feasible, or easy.
